It seems really strange and doesn't feel right
Hi. Perhaps you (like me) come from a Hammond organ background? Indeed, the drawbars of a Hammond organ are essentially volume sliders for the various pipe footages, and the volume is increased as you pull them towards you/decreased as you push them forward. Now, when you select a drawbar organ voice from the Organ World section, you will find that your Tyros’s sliders will, indeed, work in this way (pull towards you to increase/push forward to decrease). However, for all other volume changes on the Tyros, they work in the opposite way!
Regards,
Will
